CARL rrscnnnror wasrtme'rofi, DISTRICT or COLUMBIA.

To all whom it may concern Be it known that I, CARL Freeman,- a citizenof the United States, residing at Washington, in the District ofColumbia, have invented certain new and useful lmproveitherein to theaccompanying drawing.

This invention relates to improvements in draft deflecting attachments.for windows, and has for its object the provision of a simple,inexpensive device,

window andha'vadjustability, in keeping with the opening of a windowsash, the attachment being primarily designed for use at the bottom ofthe window frame in conjunction with the lower sliding sash; though, aswill i skilled in the art, the device is capable of use in, otherlocations and for other similar purposes, as for example, a shade.

The invention comprises a housing associated with suitable'side guidesadapted to be attached to'the window frame, to inclose and guide aflexible deflector associated with counterbalancing means formaintaining the shade in different positions of adjustment;

The invention furt-her comprlses a special formation of combined guide(for deflector) and way for counterbalan'cing means) and preferablyadjusting means for regulating the width of the guideway.

The invention further comprises a special formation of theguidesenablingthe beyond the edges and surfaces of the de fiectorto facilitate themovement thereof;

the deflector against. j

flanges K, K

and means for locking face-wise play to prevent rattling under theinfluence of winds, etc. I The: foregoing, as well as tithercharacteristics of improved details in the construction and arrangementof the several parts ofv the preferred embodiment of the invention fromthe detailed description hercina fter contained when-read inconnectionliwith the accompanying drawings forming'part hereof andwhereinsaid embodiment is disclosed.

. Referring more specifically to the drawings wherein like referencecharacters designate corresponding parts in the several views, Arepresents the side members of a window frame, B inwardly projectingmolding immediately adjoining ably attached to the molding C at theopposit-es'ides of the window irame and at the bottom of the latter area pair of combined guides and ways, each composed of twosheet metalmembers having flat base portions E and F, respectively, superimposedat" their inner edges and adjustably connected tothe usual sill and Cthe.

the-lower sliding sash. Removgether and to the adjacent molding C screws.G passing through horizontal slots 7 in thebase F and then through themember E and embedded in the molding C. The base E is of considerablygreater width than the base F,- approximately the width of"the ,moldingC or less than the width of siiid molding, so as not to projectforwardlythereover. The bases E and F are bent, outwardly at right angles as atH, H, the l ce jiinwardly, parallel to the base, as at L'Tato constitutean open or box-like structure forming away J 'therewithin, saidportions1, I extending in opposite directions toward eachother and terminatingin flanges K,-K', offset at right angles to the port-ions I, I- anglesrelative to the bases E and The are separated to constitute a guidewayL, the width of this guid'cway"being regulated by the relativeadjustment of the medium of the screwand-slot fastening means G+ Thebase of the guideway L is closed by carrying inwardly the portion I soas to underlie the portion I, then folding the metal upon itself acrosssaid base portion of the guideway L to constitute a verfical wall 1'terminating in the flange K. The p v 105 flanges K, K are formed withthe metal folded 'upon itself to constitute rounded ed es 1:.

he guide members, above defined, termi= and also at right hate at theirlower ends and are secured to the opposite' ends of a casing M, the samealso being formed of sheet metal'arranged ina horizontal position andhaving a flat bottom to rest upon the sill B, with a dependingv flange mfitting behind the sill B between the same and the lower sash D. The

- guide members F are connected together so as to be removable fromtheguide members E, to the lower ends of which latter, the for Ward roundedportion m of the housing or casing M is connected. The upper portion ofthe casing is open to provide a longitudinal slot a through which aflexible deflector N may pass into the casing and around aconstantly-acting spring roller 0 mounted at itslends on the endwalls ofthe casing, the usual bearings o, detachably" holding" the roller. inplace. The opposite edges of the flexible deflector are guided in thevertical movement of the latter by the guideways L, and to overcome thetension of. the'spring roller 0, counterbalancing weights P are providedsuspended from cords p in the ways J, thecords passing over, sheaves pmounted at the upper ends of the guidewavs L between the flanges K, K;the opposite ends of the'cords represented at 72 being connected to theends of the upper edge portion of the deflector N.

The deflector N is preferably formed of clothor other fabric,conveniently weatherproofed, reinforced by transverse rods of metal ainserted in pockets formed between the layers of fabric by the lines ofstitch ing 7?, and a handle is secured centrally of the upper rod tofacilitate adjusting the deflector.

From the foregoingdescription, it will be apparent that when the sash Dis raised for ventilating purposes, the deflector N may bcorrespondingly adjusted and maintained i position through the medium ofthe weights P to deflect the draft upwardly in a verticaldirectionrather than permit the same to enter the room directlyhorizontally through the window opening; also that by reason of thecharacter of the deflector the same will deflect any sudden rainoutwardlv anddownwardly away from the attachment owing to theinclination of the outer wall m I of the casin and the depending flangem thereof, whic would cause the water to flow away from the spacebetween the bottom of the casing and the upper surface'of the sill B,and any water getting into the casing, that is around the deflector,would pass out through the opening m between the inclined portion m andthe base m of the casing M.

t yrojectingbeyond the faces of the de flec'tor-and also beyond theedgethereof, are

anti-friction rollers, preferabl rubber, rep; resented at m, m",respectively, adapted to facilitate the raising and lowering of thedeflector, the rollers in engaging the flanges K, K, and the rollers inengaging the base of the guideways L,

The rollers will serve in a large measure to prevent undue vibration orrattling of the deflector under the influence of winds, but itisdesirable, in some instances, to rovide a brake or look, and to that endI pivotally mount, at the ends of the flanges K, a pair of vertical rodsR, substantial] of the same length as said flanges, provided with operating handles S. These rods are adapted to be turned inwardly, as shown indotted lines, Fig. 3, to occupy a position between the and flanges K andthe adjacent surface of the deflector to bind against theelattcr andprevent vibration of the same. The rods are further useful in overcomingany tendency of the deflector to rewind upon the constantly actingspring roller, when subjected tothe action of winds, which mightovercome the counterbalanciug ell'ect of the Weights.
